Appendix:
How the PVC System Works:
A closed crankcase ventilation system must be used in order to provide a more complete scavenging of crankcase vapors.
Filtered air from the air induction system (air cleaner) duct is supplied to the crankcase/oil reservoir, mixed with blow-by vapors,
and passes through a crankcase ventilation metering device before entering the intake manifold. The primary component in the
positive crankcase ventilation (PCV) system is the PCV flow metering orifice. Vacuum changes within the intake manifold result
in flow variations of the blow-by vapors. If abnormal operating conditions occur, the design of the PCV system permits excessive
amounts of blow-by vapors to back flow through the crankcase vent tube and into the engine induction system (air cleaner) to be
consumed during normal combustion. This engine ventilation system design minimizes oil consumption and significantly reduces
the potential for oil ingestion during vehicle limit handling maneuvers.
